Lightweight. Rugged. Engineered to Beat the Heat.

RINI Technologies’ Personal Cooling System Vest (PCS) is the most compact, lightweight, and efficient active cooling solution on the market, engineered to keep you cool under pressure.

Utilizing patented vapor compression technology, the PCS chills water to 72°F, circulating it through a Cooling Vest worn close to the skin beneath protective gear. This chilled water draws heat away from the body and transfers it to the system’s internal heat exchanger, actively lowering core body temperature, even in the most extreme environments.

Whether you're on a prolonged mission, in high-heat zones, or performing high-intensity tasks, the PCS enhances physical endurance, mental clarity, and operational effectiveness.

Key Benefits:

• Actively reduces heat stress and risk of heat-related injuries

• Helps maintain core body temperature in high-heat conditions

• Improves hydration and reduces fluid loss

• Extends mission duration and improves cognitive performance

• Lightweight and designed for rugged field operations

Technical Specifications:

• Vest Cooling Temperature: 72°F

• System Dimensions: 2.7” x 5.2” x 6.7”

• System Weight: 4 lbs (add 3.1 lbs for BB-2590 battery)
